It's Not All Of Mastery

If an expression of gross mastery is the ability to sit physically still regardless of how uncomfortable one may get, for as long as one has previously determined, then what would a corresponding expression of subtle or metal mastery be?

If mastery is the ability to choose freely which physical, emotional or psychological impulse to respond to, then would that not depend on an ability to not respond to any?

Without mastery we are driven by a compulsion to respond to almost every emotion, feeling and thought twitch and impulse, a few of which take us toward our vision, the vast bulk away.

Ask anyone and they would agree on the need for mastery. Ask the same person to explain in exact detail what it means to be perfectly psychologically still and you will at best get a vague non committal answer.

It’s not all of mastery, but mastery depends on choice and on the trained ability to consistently choose which sensation, emotion, thought and feeling to respond to, which means being able to not respond to any.
